Business Register Open Data

Estonia Business Register Open Data

Use when

• You need legal entity baseline datasets (registrations, statuses, attributes).
• You need reproducible business population extracts.
• You need organization-level context that also supports party membership trend analysis.

Avoid when

• You only need high-level macro indicators.

Access reality

• Public access type: direct downloadable snapshot files + API/X-road documentation.
• Snapshot files are directly downloadable as zipped CSV/XML/JSON/Parquet from open-data page.

Inputs

• Entity scope, date range, and required fields.

Outputs

• Registry extract with schema notes and date stamp.

Primary endpoints

• Download page: https://avaandmed.ariregister.rik.ee/en/downloading-open-data
• Open data API index: https://avaandmed.ariregister.rik.ee/en/open-data-api/introduction-api-services
• Open data guidance: https://abiinfo.rik.ee/en/e-business-register-queries/open-data-e-business-register
• Beneficial owners guidance: https://abiinfo.rik.ee/en/e-business-register-queries/beneficial-owners
• XML service WSDL (live): https://ariregxmlv6.rik.ee/?wsdl
• XML service WSDL (demo): https://demo-ariregxmlv6.rik.ee/?wsdl

Retrieval workflow

1. Open download page and choose dataset family (for example ettevotja_rekvisiidid__...).
2. Download zip file in desired format (csv.zip, xml.zip, json.zip, parquet.zip).
3. Unzip and parse with original delimiter/encoding preserved.
4. If needed, use open-data API documentation pages for query-based enrichment.
5. Keep snapshot file name and retrieval date in output metadata.

Request contract

• Snapshot downloads: direct GET file URLs under /sites/default/files/....
• API-related docs list service methods and contracts.
• XML service (ariregxmlv6) is documented by WSDL and includes paid/demo service contexts.

Output schema expectations

• Preserve at least:
• business registry code (ariregistri_kood)
• legal form/status fields
• registration date fields
• address/location fields
• source link and snapshot timestamp/file name
• Keep beneficial-owner fields separate from core legal-entity fields.

Limits and caveats

• Different datasets use different format families and completeness levels.
• API contracts and access terms can differ from static open-data snapshot access.
• Some related services (contracted APIs) are not free/open in the same way as snapshot files.

Verification hooks

• Verify downloaded archive is valid zip and contains expected table file.
• Verify header row includes key identifiers (for example ariregistri_kood).
• Verify WSDL endpoints respond with XML metadata.

Quality checks

• Preserve original business identifiers.
• Keep snapshot date and provenance in output metadata.
• Keep beneficial-owner fields and legal-entity fields clearly separated.
